摘 要: 基于发动机仿真软件BOOST开发了发动机模型,通过调整节气门流量系数和燃烧模型参数,标定了发动机万有特性.分析了BOOST发动机相对于简单发动机模型的优势,并基于国IV(I)型循环工况,将BOOST发动机在CRUISE环境中进行了应用,给出了发动机和集成式起动机-发电机(ISG)在城区和城郊路况下的动力性参数及油耗.结果表明,相对于简单发动机模型,BOOST发动机较好地仿真了发动机瞬态过程,可以有效地指导控制策略优化. The AVL BOOST engine model was developed.The engine universal characteristic was calibrated by modulating the throttle flow rate and combustion model parameters.The BOOST engine can be called by CRUISE in the background.The advantages of BOOST engine were listed.The BOOST engine was integrated in the CRUISE simulation environment under New European Driving Cycle.By analyzing the power and fuel consumption of engine and Integrated Starter-Generator(ISG) under urban and suburb cases,the result shows that the BOOST engine well simulates the engine transient process and can guide the control strategy optimization effectively.
